Texas Rangers slugger Prince Fielder is facing the prospect of season-ending neck surgery after an MRI revealed a herniated disk just above an area that was repaired two years ago.

Fielder and outfielder Shin-Soo Choo were placed on the 15-day disabled list Wednesday by the slumping AL West leaders, who had lost 12 of 16 games going into their game at the Los Angeles Angels.

General manager Jon Daniels said Fielder on Monday reported having similar symptoms to those he felt before the 2014 surgery that limited him to 42 games his first season with the Rangers. Fielder was feeling weakness and discomfort in his neck and left arm.

Fielder had played in 547 consecutive games and hadn’t missed consecutive games since August 2007 before a cervical fusion of two disks in his neck in May 2014.

Fielder is hitting .212 with eight homers and 44 RBIs in 89 games this season. Choo is hitting .260, with a .372 on-base percentage, in 33 games.

Choo missed 54 games this season during two earlier stints on the disabled list. After missing 35 games because of a right calf injury, Choo returned for only one game before going back on the disabled list with a left hamstring issue.

“With Choo, we have a little more clarity,” Daniels said. “We expect him back in a couple of weeks.”

Texas recalled infielder Hanser Alberto and outfielder Delino DeShields from Triple-A Round Rock.
